SECTION 1
PRECAUTION
1.1 Safety Precautions
(1) This design of th is product contains special hardw are and
many circuits and components specially for safety purposes. For continued protection, no changes should be made
to the original design unless authorized in writing by the
manufacturer. Replacement parts must be identical to
those used in the original circuits. Services should be performed by qualified personnel only.
(2) Alterations of the design or circuitry of the product should
not be made. Any design alterations of the product should
not be made. Any design alterations or additions will void
the manufacturers warranty and will further relieve the
manufacture of responsibility for personal injury or property
damage resulting therefrom.
(3) Many electrical and mechanical parts in the products have
special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the
protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special
safety characteristics are identified in the Parts List of Service Manual. Electrical components having such features
are identified by shading on the schematics and by ( ) on
the Parts List in the Service Manual. The use of a substitute
replacement which does not have the same safety characteristics as the recommended replacement parts shown in
the Parts List of Service Manual may create shock, fire, or
other hazards.
(4) The leads in the products are routed and dressed with ties,
clamps, tubings, barriers and the like to be separated from
live parts, high temperature parts, moving parts and/or
sharp edges for the prevention of electric shock and fire
hazard. When service is required, the original lead routing
and dress should be observed, and it should be confirmed
that they have been returned to normal, after reassembling.
(5) Leakage shock hazard testing
After reassembling the product, always perform an isolation check on the exposed metal parts of the product (antenna terminals, knobs, metal cabinet, screw heads,
headphone jack, control shafts, etc.) to be sure the product
is safe to operate without danger of electrical shock.Do not
use a line isolation transformer during this check.
• Plug the AC line cord directly into the AC outlet. Using a
"Leakage Current Tester", measure the leakage current
from each exposed metal parts of the cabinet, particularly any exposed metal part having a return path to the
chassis, to a known good earth ground. Any leakage current must not exceed 0.5mA AC (r.m.s.).
• Alternate check method
Plug the AC line cord directly into the AC outlet. Use an
AC voltmeter having, 1,000Ω per volt or more sensitivity
in the following manner. Connect a 1,500Ω 10W resistor
paralleled by a 0.15µF AC-type capacitor between an exposed metal part and a known good earth ground.
Measure the AC voltage across the resistor with the AC
voltmeter.
Move the resistor connection to each exposed metal
part, particularly any exposed metal part having a return
path to the chassis, and measure the AC voltage across
the resistor. Now, reverse the plug in the AC outlet and
repeat each measurement. Voltage measured any must
not exceed 0.75 V AC (r.m.s.). This corresponds to 0.5
mA AC (r.m.s.).

1.2 Warning
(1) This equipment has been designed and manufactured to
meet international safety standards.
(2) It is the legal resp onsibility of the repairer to ensure that
these safety standards are maintained.
(3) Repairs must be made in accordance with the relevant
safety standards.
(4) It is essential that safety critical compone nts are replaced
by approved parts.
(5) If mains voltage selector is provided, check setting for local
voltage.
1.3 Caution Burrs formed during molding may be left over on some parts
of the chassis.
Therefore, pay attention to such burrs in the case of preforming repair of this system.
1.4 Critical parts for safety
In regard with component parts appearing on the silk-screen
printed side (parts side) of the PWB diagrams, the parts that are
printed over with black such as the resistor ( ), diode ( )
and ICP ( ) or identified by the " " mark nearby are critical
for safety. When replacing them, be sure to use the parts of the
same type and rating as specified by the manufacturer.

1.5 Important for laser products
1.CLASS 1 LASER PRODUCT
2.DANGER : Invisible laser radiation when open and inter
lock failed or defeated. Avoid direct exposure to beam.
3.CAUTION : There are no serviceable parts inside the
Laser Unit. Do not disassemble the Laser Unit. Replace
the complete Laser Unit if it malfunctions.
4.CAUTION : The compact disc player uses invisible laser
radiation and is equipped with safety switches which
prevent emission of radiation when the drawer is open and
the safety interlocks have failed or are de
feated. It is dangerous to defeat the safety switches.
5.CAUTION : If safety switches malfunction, the laser is able
to function.
6.CAUTION : Use of controls, adjustments or performance of
procedures other than those specified herein may result in
hazardous radiation exposure.
!
Please use enough caution not to
see the beam directly or touch it

When the main body is set to JIG mode and when the main body is under JIG mode, the remote control unit attached to DR -M1SL
operates only in "Remote Control Code 1". Since DR-M1SL is in "Remote Control Code 3" when it is shipped and just after its batteries
are changed, "Remote Control Code 3" needs to be changed to "Remote Control Code 1."
< Changing Remote Control Code >
(1) Switch TV/CABLE/SAT/DVD Switch to "DVD"
(2) Press the numeric button "1" of the remote control unit whil e pressing the "SET UP" button of the remote co ntrol unit. Then,
press the "ENTER" button, and then release the "SET UP" button.
(3) Press the "PLAY" button of the main body for five seconds or longer while the main body is in stand-by mode, and a curre nt
remote control code of the main body is displayed in FL indicator of the main body.
(4) While keeping the state of (3), press the "STOP" button of the remote control unit toward the main body.
(5) When FL indicator displays "DVD1," it means that the Remote Control Code has been changed to "1."
*DR-M1SL has remote control codes of 1, 2, 3, and 4.
*The remote control codes "DVD 1, 2, 3, and 4" of DR-M1SL are the same as the remote control codes

5.1.4 Upgrading firmware of the main body
• Firmware upgrade disk supports only DVD-RAM media.
• When firmware needs to be upgraded, Optical disc CSG will distribute a firmware upgrade disk.
(1) Set the main body to JIG mode.
(2) Transmit "43-70" to the main body by using JIG remote control unit.
(3) "UPDATE" appears in FL indicator. Load DVD - RAM disk for upgrade on the tray, and close the tray.
(4) Wait for approx.30 seconds while FL indicator is displayed as "UPDATE."
(5) Then, "FW UPDATE" appears in FL indicator. It takes approx. 3 minutes at maximum to upgrade firmware.
(6) The tray is ejected. Then, take out the disk and close the tray.
(7) Turn the main body OFF, and pull out the power cord from the wall socket. The n, plug the power cord into the wall socket.
(8) "LOADING" of FL indicator disappears. Then, turn the main body ON.
(9) Display the SYSTEM INFO menu, and check the version of the firmware.
(10) Cancel JIG mode.
ATTENTION :
Firmware may sometimes not be upgraded successfully.
If firmware is not upgraded successfully, the tray opens, and "ERROR" appears in FL indicator.
If firmware is upgraded successfully, the tray opens, and "OPEN" appears in FL indicator.
If the power cord is pulled out from the wall socket while " ERROR" appears, data in the flash memory is destroyed and the main
body cannot start: the flash memory needs to be replaced.
After upgrading procedure, pay enough attention to FL indicator when the tray opens.
When "ERROR" appears, upgrade firmware again in the following way to restore the firmware.
(1) Transmit "43-70" to the main body by using JIG remote control unit while the tray opens.
(2) When "UPDATE" appears in FL indicator, close the tray and make the main body read the disk. Upgrading starts.
(3) After (2), perform upgrading procedure (4) - (10) of 5.1.4 Upgrading firmware of the main body above.
